The movement is uniform and smooth. Laminar flows mainly occur at low flow velocities and with highly viscous media.<\/p>\n<p>Typical for laminar flows is a comparatively low internal exchange within the medium. As a result, mixing is slower, but at the same time significantly lower shear forces act on the product.<\/p>\n<p>Examples of laminar flows include:<\/p>\n<ul>\n<li>the blood flow in fine blood vessels<\/li>\n<li>the movement of groundwater<\/li>\n<li>the slow flow of highly viscous media<\/li>\n<\/ul>\n\t<div class=\"img has-hover x md-x lg-x y md-y lg-y\" id=\"image_519519189\">\n\t\t\t\t\t\t\t\t<div class=\"img-inner dark\" >\n\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"1722\" height=\"315\" src=\"https:\/\/ptm-mechatronics.com\/wp-content\/uploads\/2024\/09\/Laminar.jpg\" class=\"attachment-original size-original\" alt=\"\" srcset=\"https:\/\/ptm-mechatronics.com\/wp-content\/uploads\/2024\/09\/Laminar.jpg 1722w, https:\/\/ptm-mechatronics.com\/wp-content\/uploads\/2024\/09\/Laminar-300x55.jpg 300w, https:\/\/ptm-mechatronics.com\/wp-content\/uploads\/2024\/09\/Laminar-1024x187.jpg 1024w, https:\/\/ptm-mechatronics.com\/wp-content\/uploads\/2024\/09\/Laminar-768x140.jpg 768w, https:\/\/ptm-mechatronics.com\/wp-content\/uploads\/2024\/09\/Laminar-1536x281.jpg 1536w, https:\/\/ptm-mechatronics.com\/wp-content\/uploads\/2024\/09\/Laminar-18x3.jpg 18w, https:\/\/ptm-mechatronics.com\/wp-content\/uploads\/2024\/09\/Laminar-100x18.jpg 100w, https:\/\/ptm-mechatronics.com\/wp-content\/uploads\/2024\/09\/Laminar-447x82.jpg 447w, https:\/\/ptm-mechatronics.com\/wp-content\/uploads\/2024\/09\/Laminar-810x148.jpg 810w\" sizes=\"auto, (max-width: 1722px) 100vw, 1722px\" \/>\t\t\t\t\t\t\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\n<style>\n#image_519519189 {\n  width: 100%;\n}\n<\/style>\n\t<\/div>\n\t\n\t\t<\/div>\n\t\t\t\t\n<style>\n#col-832242801 > .col-inner {\n  padding: 20px 20px 20px 20px;\n}\n<\/style>\n\t<\/div>\n\n\t\n\n\t<div id=\"col-1695223376\" class=\"col medium-6 small-12 large-6\"  >\n\t\t\t\t<div class=\"col-inner box-shadow-3\" style=\"background-color:rgba(0, 0, 0, 0.488);\" >\n\t\t\t\n\t\t\t\n\t<div id=\"text-2858312107\" class=\"text\">\n\t\t\n<h3>What are turbulent flows?<\/h3>\n<p>As the flow velocity increases, increasingly irregular turbulence occurs within the medium. The previously ordered layered structure dissolves and the fluid moves chaotically in all directions. This is referred to as turbulent flow.<\/p>\n<p>Turbulent flows ensure an intensive exchange of substances and heat and enable effective mixing. In agitator technology, this effect is often supported by installations in the tank, such as so-called baffles.<\/p>\n<p>Typical examples of turbulent flows are<\/p>\n<ul>\n<li>Milk poured into
